1. Use DAC60508ZRTET to output 0~5V, circuit as the pucture.
2. Internal reference 2.5V by default, DMM measure 2.5V(About 2.496V) on PIN1(REF) of some chips, but others is 2.38V.
3. Change C903(1uF) to 470nF or 2.2uF, voltage not change on PIN1(also 2.38V)
Could you help me analyze this issue? Is it circuit issue or chip issue?
Thanks a lot!
